21 d = 1.8144e+15 ns
Full precision:1.8144e+15 ns
Step-by-Step Solution
To convert 21 days to nanoseconds, we multiply by 8.64e+13 because one day equals exactly 8.64e+13 nanoseconds.
1 day = 8.64e+13 nanoseconds
Since each day contains 8.64e+13 nanoseconds, we multiply our value by this factor:
21 × 8.64e+13 = 1.8144e+15 nanoseconds
So 21 days = 1.8144e+15 nanoseconds.
Quick check: 1.8144e+15 ÷ 8.64e+13 = 21 days
